Apple Stops Signing iOS 15.5 Following iOS 15.6 Release, Downgrading No Longer Possible

Following the launch of iOS 15.6 last Wednesday, Apple has stopped signing iOS 15.5, the previously available version that came out in mid-May. Since iOS 15.5 is no longer being signed, it is not possible to downgrade to that version of iOS after installing iOS 15.6.

iOS 15
Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date, so it is not unusual that iOS 15.5 is no longer being signed.

iOS 15.5 was a relatively small-scale update, with improvements to Apple Cash in the Wallet app and a new setting that lets Podcasts users limit the number of episodes stored on their devices.

Released on July 20, iOS 15.6 was a similarly minor update and introduced a handful of features including an option to restart, pause, rewind, and fast-forward a live sports game that's in progress. It also addressed some small bugs, including an issue that could cause the Settings app to continue to display that device storage is full even when it's not.

After upgrading from iOS 14.8.1 to iOS 15.6 on my iPhone 11 Pro Max my two main complaints are I have to constantly toggle airplane mode to restore LTE service, it keeps going dead, never had this issue on iOS 14.

Second is the notifications, when long pressing on a notification to see more details there’s no longer an option to clear (X) it but you have to tap in the grey area to dismiss and then swipe from right to left to clear it and then move on to the next one. Extra steps that slow down the interface.

There’s a few visual display bugs like swiping up in the notification area shows a grey box at the top and safari address bar at the bottom in privacy mode jumps when scrolling favorites.

Hopefully the EU compels Apple to require permanent downgrading capability. If I don’t like iOS changes, why can’t I go back to a better version for my device (accepting possible security issues).
